Particle-Size Effects on the Volatilization of Oil in Porous Media

Abstract:

The volatilization process of oil with uniform size media as underlying material was studied. The weight loss of oil was determined by subtracting the columns’ pre and post weight measured on an electronic balance. The results show that the gasoline in porous media volatilizes at a logarithmic rate with respect to time, and the diesel oil in porous media volatilizes at a rate which can be best modelled as a square root of time. The volatilization coefficient of gasoline increases with the increment of particle size, and it of diesel oil decreases with increment of particle size. Binomial equation and power equation can describe the relationships of gasoline and diesel oil volatilization coefficients with mean grain size respectively.
